 The output format of the script should be one symbol per line:
 
-  <name> <type> <lang> <line> <path>

 For example:
 
-  ExampleClass class php 13 /src/classes/ExampleClass.php
+  ExampleClass exampleMethod function php 13 /src/classes/ExampleClass.php

+Context is, broadly speaking, the scope or namespace where the symbol is

+symbols with that context are class constants, methods, properties, nested
+classes, etc. When printing symbols without a context (those that are defined
+globally, for instance), the ##<context>## field should be empty (that is, the
+line should start with a space).
 
 Your script should enumerate all the symbols in your project, and provide paths
